The weather is all mist and clouds at the moment. So almost no energy from the solar panels.
The weather will change someday.. I just know it! ;)

We decided for the solar panels to do our tiny bit for the environment and to save on our electricity bill. Also, I think in the near future energy prices will rise to new heights as Earth's oil, coal and gas supplies are running low.
So it is a good thing to be able to provide some of our own energy.

UPDATE: December 29th.
I just realised... this was the last comic of 2006 and the last comic of the first year of Raising Zoe.
